Description

Technical Field

[0001] The utility model relates to the technical field of correctable laser mapping devices, in particular to a correctable laser mapping device. Background Art

[0002] Laser surveying is used for surveying work in the planning, design, construction and operation management stages of engineering construction, such as various orientation, distance measurement, angle measurement, height measurement, mapping and photogrammetry. When measuring some nodes, a laser surveyor is required to measure at fixed calibration points.

[0003] In the existing laser surveying and mapping, after the installation is completed, when the horizontal position of the surveying and mapping device is corrected, the support frame needs to be moved, which affects the horizontal inclination of the surveying and mapping device and is not conducive to the correction of the position of the surveying and mapping device.

[0004] A correctable laser surveying and mapping device based on engineering surveying and mapping is disclosed in the Chinese utility model patent application disclosure CN219389278U. Although the correctable laser surveying and mapping device based on engineering surveying and mapping has the advantages of convenient angle correction and reduced errors, the correctable laser surveying and mapping device based on engineering surveying and mapping still has disadvantages: First, the correctable laser surveying and mapping device based on engineering surveying and mapping uses a connecting rod module to adjust the overall height through a knob control. In actual use, the three supporting legs may not be adjusted synchronously and at the same height during the height adjustment process, and errors may be caused by slight height differences between the supporting legs during the adjustment process; Second, the correctable laser surveying and mapping device based on engineering surveying and mapping is often used at construction sites. The ground at the construction site will vibrate due to abnormal vehicle passing, and these vibrations may cause errors in the surveying and mapping device during detection. Utility Model Content
